SALLES, William N. et al. Influence of age and maturation on perceived collective efficacy in youth basketball players. CPD [online]. 2019, vol.19, n.1, pp.275-282.  Epub 17-Ago-2020. ISSN 1989-5879.

Growth and maturation impact the development of young athletes' physique and function, and may also influence their psychological and behavioral characteristics. Collective efficacy (CE), a psychological measure and potential mediator of sports performance, may be influenced by maturity status. However, there is scarce information available regarding young players' perceptions of CE and the relationship between the CE and the young athletes' maturity status. Therefore, this study examined the perceived CE variation between young basketball players accounting for the influence of chronological age and biological maturity status. The sample included fifty-seven adolescent basketball players aged 9.5 to 15.5 years. Chronological age, estimated age at peak height velocity (PHV) and CE through the Portuguese version of the Collective Efficacy Questionnaire for Sports were considered. Bayesian multilevel modeling was used to examine the athletes' perceived CE dimensions variation by age and maturity status. Overall, the adolescent basketball players' perceived CE scores were high for all dimensions: ability (8.77±1.15); effort (9.20±1.03); persistence (8.87±1.18); preparation (8.96±1.08); unity (8.88±1.22). The variability estimates were very large, suggesting that the influence of maturity status on variation may be residual. There was no substantial relation between chronological age and the CE variation scores, although the results suggest that perceived variation was independent of chronological age variation and between players variation in maturity status. Given the small, localized sample investigated, further studies examining the relations of chronological age, maturity status, and perceived CE are suggested for better understanding the young athletes' development in sport.
